Re: [TM4J-users] Beginner: Problems importing topic-map file

[Kal A. <ka...@te...>]

Hi Martin,

I'm glad you managed to fix your problem - but the error messages wasn't 
really very helpful, was it ? ;-) If you could let me know which libs were 
missing, perhaps I can track down where the bad error message gets 
generated and try and improve things.

Cheers,

Kal
